“…There are a few different methods that can be used to evaluate the flatness of a surface plate. The most typical way to assess whether a surface is flat is to utilize an instrument capable of detecting small angles, e.g., an autocollimator, a laser interferometer, laser scanning, or a leveltronic [15][16][17][18][19] .…”

The surface plate is a physical flatness reference that widely used in research and industrial applications, e.g., manufacturing, aerospace, automotive, and shipping engineering. Surface plate calibration is required; as a result to guarantee that it continues to fall within the parameters of what is considered to be an acceptable level of flatness. In most cases, Union Jack Moody's approach is relied on to gather data and determine the level of flatness and the Grid method is not widely recognized. The Grid technique can be broken down into two patterns: the Open Grid and the Full Grid. Spreadsheet application is utilized to processing flatness data with the Open Grid approach. A piece of computer software, e.g., Scilab or another program that can perform calculations with matrices, is required. Unlike the Open Grid technique, which has a greater degree of uncertainty, the Full Grid technique has a reduced degree of uncertainty. This study aims to report on assessing the surface plate flatness using two different types of Grid techniques. A surface plate measuring 1000 mm×1000 mm, as one of the measurement samples, was used to characterize both approaches. Open Grid and Full Grid measured the surface plate's flatness to be (6.93 ± 3.94) μm and (6.44 ± 0.68) μm, with Full Grid measuring it more accurately than Open Grid. It is consistently statistically shown that the En value is less than 1, which is 0.06 and 0.01, respectively. In conclusion, it can be said that statistically, the Full Grid method, as one of the proposed surface plate calibration methods, is considered an inlier result with smaller uncertainty.
